Roberts, for Casement window operators, filed .A ril 23, 1927 whichissued as Patent'No.v *.1, 44,341 on January 21,l 1930.k This operav torconsists essentially of the supportlng` housin 15, adapted to be securedtothe wintaining a wormv 18,*r rotatably supported' to window.`

actuate a worm gear 19'secured vto an arm 20.

- Thearm 20 carriesa slider 21 in its end which is adapted to slide invak guide 22 and when.

the worm 18 is` actuated b means of the hanvdle 2,3, the arm 20 isaapted to ymove the slider 21 in its guide 22 to open or close the I donot wish to limit myself to any form of operator, however, as my closurefastener maybe ators. Y

`My invention is of particular importance,

however, with an operator which is ada ted to vact upon and secure onlyone edge o the easement window, the closure fastener serving to insurethe closure of other edges and to secure them.

VIn the embodiment shown in Figures 1 and 2, the closure fastener mayinclude a shaft 24 rotatably supported by the closure and preferablylocate adjacent the edge which has the''greatest range of movement,since the complete closure of this edge will insureclos-i ing'allaroundv thel window. v

he shaft 24 may be carried by a pair of j brackets 25 and 26 of sheetmetal bent to Y wardly form kbearings for said shaft and having outtothe window or other support.

The shaft 24 may beprovided at one end with a cam 28 which is preferablysymmetrically formed uponv both sides as at 29 so'that it is adapted tobe used on right-hand or left-hand windows.

-The cam 28 is formed with a hub 31Which a may be secured tothe shaft 24either by pro- Y ce viding a non-circular end on saidshaft `in aycomplementary aperture or by a setscrew' 32.v

The set screw hasthe advantage of permitting adjustment ofthe cam toinsure complete closing under anvl condition -j of installation,

- -butiit is also possible'to so locate the brackets or shouldersagainst which the'cam lacts so that no adjustment is required.

strain when the lower edge ofthe windowis broughtinto yengagement withthe cain 28 and the `upper army33 engages shoulderk 46 to pullthefreeedge yof the window shut.

The provision of'such av torsional member enf kables mefto `do awaywithpivoted joints in employed withmany forms of operextending flanges 27,for attachmentv v28 is; engaginig VThe shaft 24 is also provided with aclosn ing arm 33 consisting of a' lever having a hub 34 provided lwith abore 35, ladapted toyreceive the shaft Y24,to which it maybe affixed inthe same'manner as described for the cam 28.v The bore 35 maybecounterbored, as at 36, and thewalls of said counterbore may be cut awayas at 37 `to permit access to a spring 38. w

The spring 38 may consist of a helical spring adapted to bereceivedinthe counterbore 36 about theshaft24, and having .one end secured inthe yslot 3 9 in the arm 33, and

the other end 'extending fromA the counter-v bore vin the cut-out 37 toengage thewindow or other fixed part. The spring 38 is, therefore,adapted to bias the shaft 24 with its cam 28 and arm33 ina clockwisedirection in Iiigure 2, rotation ofthe shaft being limited by a stop 40,consisting of a pin projecting from either hub and engaging the windowor other fixed part. The cam land arm are shown in this limitin positionin dotted lines in Figure 2; It shoul ,also be noted that the hubs 34and Land a bracket 42vadapted to engage the arm 33.

y These brackets may consist of sheet metal members having an att-achingfiange 43 secured lto the closure support by a plurality of screws 44,and having an upwardly extending flange 45 at substantially right anglesto the attaching flange '43; VThe bracket 42,

which may be of similar structure, is attached to the closure support,in vthe present in-` stance, at thevtop ofthewindow frame with theflange 46 projecting downward in position to be-engagedV by the arm 33.The arm 33 shouldfengage on theopposite side of the flange 46 from thewindow 13, in such manner that counter-clockwise rotation of the shaft24 in` Figure 2 will cause the arm to engage thefixed flange 46 andvreact yagainst window frame in positiontobe engaged by the cam 28, andthe location of the flange 45 should besuchthat when the lower edge ofthe window is completely closed and the cam the flange- 45, the yarm hasengaged the ange 46 and firmly vpulled the .upper edge of the windowinto closed position.` The shape ofthe cam 29 may be made such thatfriction is greatlyy reducedl by a single point contact between the camand i A4l f direction. VAs the closing" movement, profl gresses therelation of the parts is such that'V spring to bias it to the .positionshowninf the arm` 33 rota-tes in behindfthe flange 57 and ywhenthe loweredge ofthe windowhas been moved to closed position, the upper edge isalso forced to 'such position'by enga-gement of the arm 33v behindV the'flange `57. My closure 'fastener not only vforces .the remote n Y Yupperedge ofthe window intocl'osedjposi# tion, but secures it in suchposition as long as thewindow is secured bythe bolt 57 a.

' While I have illustrated my device with a Figure 5, many yof t-headvantages 'of my Y fastener may be realized without employing a spring,since it will be noted that when the y window; 48 is openedfrom'the'position yin Figure4, the flange v57 will naturally force theylarm -33 counter-clockwise, moving the cam andarm to the position shownin Figure 5. When thel parts are in this position they are alreadydisposed so that the arm 33 will automatically enter behind the flangek57 when the Window is closed and it will be evident that thedevicew'ill operate without employing a,V spring. On the other hand the.spring insures thelocation of the mechanism in proper position atalltimes and is therefore included in the preferred embodiment.

Itshouldalso be noted that the linger 33 `is preferably made of greaterlengthothan the cam 28 in order that theend of the finger may have a,wider range of movement `during thesame timethat thecam moves. Thus thefinger moves'farther than the cam` andis adapted to take up any llagcaused by .the warping ofthe window. f v

It should also be noted that .where a fastening bolt, such as is used inFigureT 6, is employed on a steel window, thekeeper 61 may be eliminatedandthefend 59 ofthe bolt may` react directly against the flange whichforms the lower edge ofthe window frame.

f -It willy thus be observed that I. havein vented aV closure fastenerwhich automatically securestheupper or remote edgev of the window whenthe lower edge is closed and which; is adapted to prevent any warping ofthe window or unauthorized opening= from thenpper edge. It should alsobe noted that my inventionmay-be applied'to' left-hand and right-handwindows or tosingleor double n windows ory other types of "closures, andit may readily be used with any size: of window since the shaft 24 mayVbe constructed of sheet metal'pipe which may be cut tothe proper lengthbyjan ordinaryhacksaw on the J'ob. f

My closure fastener is actuated by apart of the same window on which the',fasteneritself reacts, and the simple and effective structuredescribedis capable of long service without deterioration or necessityfor adjustment. The torsion shaft makes the entire mechanism resilientand the fixed arms orfingers carried `by the shaft may beadjusted so asto satisfactorily close and secure .any Window vor lother closure. n v..i Y i While I have illustrated and described a specific embodiment ofmy invention, many modificationsmay be made without departing from thespirit of the invention, and I ido not wish to be limited to `theprecisede.- Y
